Pillow, many years ago I watched a bride walk down the aisle, about to marry my heroin addicted friend. I knew how bad it was...and it WAS bad...and I had not lied, but I had said nothing.
I've always regretted that and since I cannot say "I am sorry" to that poor bride, I will say it to you. I am sorry, Pillow, for all those who didn't let you know the sad truth, no matter how good their intentions.
My friend's wife lasted less than a year, her heart was broken but today she is happily remarried to a wonderful man who doesn't ever drink or do drugs and never did.
I pray that you can find your way through this, I can only guess how painful this all is for you. But you did the right thing.
Leaving a marriage where addiction lives is like closing a door on an already empty room.
You will be okay, you are stronger and wiser and you can hold your head high. Anyone who judges you is not worthy of your friendship.
Hugs
